Abstract

A hydrostatic mechanical power-split transmission with a continuously variable gear ratio comprises a hydrostatic transmission part ( 1 ) consisting of a first hydrostatic unit ( 13 ) with an adjustable volume, a second hydrostatic unit (A) with a constant volume, and a mechanical transmission part ( 2 ) comprising a summing transmission and a range transmission, the summing transmission and the range transmission are arranged in an axially staggered manner in relation to the hydrostatic units.
